IEEE8021-MSTP-MIB
AI MIB Summary
The IEEE8021-MSTP-MIB enables the monitoring and configuration of IEEE 802.1Q Multiple Spanning Tree (MSTP) instances, specifically tracking MST region definitions, instance-to-VLAN mappings, and port state transitions across bridged network devices. It provides granular visibility into MSTP topology convergence, including root bridge election status, path costs, and port roles (designated, root, blocked) to ensure loop-free Layer 2 redundancy.
The Bridge MIB modules for managing devices that support IEEE Std 802.1Q multiple spanning tree groups.

ieee8021MstpVlanTableIn an MSTP Bridge, the fixed-length (4094 elements), read-only,
MST Configuration Table. Its elements are derived from other
configuration information held by the Bridge; specifically, the
current state of the VID to FID Allocation Table (8.8.8,
12.10.1),and the FID to MSTID Allocation Table (8.9.3, 12.12.2).
Hence, changes made to either of these Tables can in turn affect
the contents of the MST Configuration Table, and also affect the
value of the digest element of the MST Configuration Identifier.
